This hub is the shaft-side half of a two-piece coupling and is designed to pair with the matching ATRA-FLEX ring to form a complete flexible drive connection that helps accommodate minor shaft misalignment and cushion shock loads during operation. The A5 designation identifies the hub size within the ATRA-FLEX A-Series, which uses a common mounting interface across the family to simplify selection and replacement. The bore size of 1.750 inches defines the shaft diameter this hub is intended to fit, and the A-Series design provides a robust, shaft-mounted interface that supports reliable torque transmission when paired with the appropriate ring half and fasteners. For exact compatibility, use with the corresponding ATRA-FLEX A5-series ring and follow the manufacturer's installation guidelines to ensure proper clamping, alignment, and secure fastening. \u003c\/p\u003e\u003c\/div\u003e","brand":"ATRA-FLEX","offers":[{"title":"New","offer_id":51660344721710,"sku":null,"price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6e72f51a-81d1-404c-8034-d474d4a0be74.jpg?v=1769536508","url":"https:\/\/plgautomation.com\/products\/atra-flex-a5-hub-1-750-hub","provider":"PLG Automation ","version":"1.0","type":"link"}
